Hi Daren,
Welcome. The first thing you need to decide is what class you want to race. Check out the tracks you want to race at, confirm what classes they offer for your age, budget, and experience. From there, you go on to buy a kart/engine, and then hit the track.
For more specific questions, check out our 4-Cycle section of the forums.
You can check out ckikarts.com for more information on what is available to get you started with a kart, as I believe that is close to where you are. Good people.
